Detailed Description
Example 1
The scheme of the invention is that the window sheet is easy to replace, when the window sheet is polluted by the gas to be detected in the gas chamber, the window sheet can be replaced, the purging function is added to the window sheet, the window sheet is prevented from being polluted by the aging of the equipment, and the service life of the lens is prolonged.
Window piece: the gas chamber is arranged at the periphery or inside of the gas chamber, and 100% of light emitted by the light source conveniently passes through the cavity of the gas chamber while the gas detected in the gas chamber is isolated from the external environment.
Light source: and a transmitting end of the optical signal.
Pollution: the attachment causes a reduction in light transmittance of the window sheet.
A spectral analysis system: and comparing the optical signals before and after the absorption of the gas to be detected, and calculating the content of the gas to be detected.
And (3) crystallization: the gas solidifies from the gaseous state to the solid state as the temperature is reduced.
The device provided by the invention is convenient to replace, does not need to be fastened by screws, is convenient to replace on site, and has a purging function, so that the pollution caused by the aging of equipment can be avoided.
The air chamber device provided by the invention comprises an air chamber, a gland, a sliding block assembly, a valve block and a base.
The gland is rotatably and fixedly connected with the air chamber through bottom fixing ports at two sides and a rotating shaft, and two sides of the upper part are connected through a hinge with one end fixed at the upper fixing port and a hinge with the other end fixed at the air chamber; the window piece fixing device is characterized in that window piece carriers are arranged in the middle of the two hinges, two window piece fixing openings are formed in the window piece carriers, the size of an opening, close to one side of the air chamber, of each window piece fixing opening is smaller than that of each window piece, the window pieces are guaranteed to be fixed in the window piece fixing openings, the size of an opening, on the other side of each window piece fixing opening, is matched with the size of each window piece, and the window pieces can be installed and taken down. When the window is replaced, the window carrier is connected to the air chamber pressure cover by hinges at two sides.
